Прошу помощи.
Есть коммуникатор Samsung Galaxy Note на Android ICS 4.0.3 (прошивка сток, ядро CF-Root-SGN_XX_SEB_LQ3-v5.6-CWM5).
# uname -a

Требуется подключить к нему адаптер USB-Eth на ASIX AX88772B. Коммуникатор имеет порт micro-USB, подключаю через USB-OTG.
Исходники драйвера есть. В комплекте сам модуль и axusbnet.c (как я понял, замена стандартного usbnet.c).
Исходники ядра есть.
Собирал arm-2010q1.
Подключаю адаптер:

В обоих случаях видно, что засада в mac-адресе (его как-бы нет, что приводит к невозможности его удаления - если я правильно понял).
Подскажите, что и где подправить.
Или хотя бы в каком направлении искать.
